Models

This page lists the SDK's data models (the page name utilities is a legacy name; the content is Models). All models are imported from ssi_sdk.models:

from ssi_sdk.models import Account, OHLCData, PlaceOrderResponse, TradeMessage

Every model is a dataclass. A field typed X | str | None means the SDK returns the enum member when it recognises the value, the raw string when the value is unknown, and None when the server did not send it. For the enums see Enums.
